The Telaire 7001 handheld carbon dioxide sensor features patented Absorption Infrared technology. Each sensor measures CO2 and temperature and can calculate and display real-time ventilation rates. When combined with the HOBO U12 or ZW Series it can record CO2, and when connected to the H22 or U30 Series it can record temperature and CO2. The Telaire comes with an adapter but also operates up to 70 hours on 4 AA batteries (not included).
